SPINNING-RINGS.- Y

Specification forming part of Letters PatentNo. 180,611, dated August 1,1876; application led May 26, 1876.

To all whom it may concern Be it known that I, WLLLIAM H. MAGEE, ofWoonsocket,in the county of Providence and State of Rhode Island, haveinvented an Improved SpinningRing, of which the following is aspecification:

This invention relates to a spinning-ring, and has particular referenceto the position or 1 location of the'race on which the traveler runs.

The office of the traveler in spinning is to j produce drag on thethread, keep it smooth and uniform, and permit it to be wound on thebobbin as tightly and evenly' as possible, without breaking orstretching the thread, which is directed by the traveler to the bobbinas the ring-railis raised and lowered.

In the ordinary ring the thread meets thev traveler near its center, andthe centrifugal force of the traveler, in its rapid rotation, issufficient to cause the outer end ot the trav' eler to rise and drag itsinner end against the 1 inner side of the ring and under side of therace, while the' outer-end runs clear of the race, the frictionproducedbein' g, therefore, on but one end of the traveler, which causesthe traveler to move unsteadily, or oscillate at its outer end, causingan unsteady drag on the thread, which breaks it or makes it. rough, andthe traveler so lifted is sometimes pulled or thrown from the race.

Sonie -rings have been provided with inclined and beveled races,arranged at the inner portions of the rings, as in United States PatentsNos. 24,681 and 24,169; but it will be noticed that the strain of thethread on the traveler and the action of centrifugal force tend to liftthe traveler, and cause it to bear at its inner and lower end againstthe ring with greatest force.

A race arranged lower on the inner than the outer portion of the ringobstructs the winding operation, and the draft cannot be made as steadyand uniform as it would were the race located lowest at the outerportion ofthe ring.

Figure l represents one of my improved rings in section and applied to abobbin, and Fig. 2 represents a section of au ordinary racel and atraveler.

My improved ring is provided at top with an outwardlyinclined race, a,on which is placed a traveler, b, through which the thread c is led, itpassing from the usual guide-eye through the traveler and onto thebobbin, tube, or spindle. This race is inclined, substantially as shownin the drawings, and is provided at its inner portion with an inclinedor rounded way, c, against which the inner end of the traveler moves;and at its extreme outer edge f the traveler is rounded or chainfered,to permit the thread toengage the traveler very close to its inner end,and so that the yarn extending from the bobbin to the trav- 4eler willbe substantially on a level with the extreme upper' edge g of the innerange, such edge being located in a circle of larger diameter than thecircle formed by the annularlyprojecting portion h, just below the edgeg.`

By constructing the race and placing it in an inclined position,substantially as described andl shown, and so that the traveler, in itsrotation'about the race, will, owing to its cen- 'trifugalactioin keepboth its ends against the ring, I am enabled to use a very lighttraveler, and one by which the uniformity of the drag on the thread maybe increased, for when both ends of the traveler bear constantly on thering it will loe` obvious that its motion will be more uniform andsteady, and it will not oscillate as does the traveler on an ordinaryring, so constructed that both ends ofthe traveler fail to find aconstant bearing thereon.

Another important advantage gained by the location of the race asdescribed is that the yarn is enabled to encircle and pull against thetraveler much nearer its inner end than has been heretofore the case,and this insures a steadier draft than is the casewhen the yarn passesabout a traveler near its center.

The centrifugal action of the traveler, in connection with the upwarddraft of the yarn, tends to keep thc outer end ofthe traveler alwaysagainst the outer portion of the ring-race, and the force with which theinner end of the traveler bears on the ring is varied according to thedraft between the bobbin and traveler. When the bobbin first receivesthe thread the yarn extending from the bobbin to the traveler assumes aposition with relation to the circumference of the bobbin more nearlythe bobbin is being filled, for the spindle turns' at the same speed;but when the yarnisgbeing.

Wound on the bobbin, the latter being small, the draft onthe yarn issuiicienhand it acts to pull the traveler toward the then outer portionof the bobbin, which is then nearer the center of the ring than when thebobbin is mostly filled; and this inwarddraft, although insufficient toremove the inner end ofthe traveler from the race, does act to lessenthe amount of its friction on the inner portion 'of' the race, makingthe friction :less than `when the yarn, proceeding from the full bobbin,acts on the traveler, for then the centrifugal action of the traveler,being less impeded,enables they traveler to bear at its inner end withgreater -force than when Athe bobbin is first ,being Wound, and in thisWay the draft on the yarnV and centrifugal action of the traveler tendto vmake the drag on the yarn and thewinding action more nearly uniformthan is :the case with the ordinary ring and traveler, and va very lightvtraveler may be used.

Ring-travel ers h ave frequently to be changed according to the sizeofthe yarn or thread; but in all cases with aring and travelerconstructed as above described, thevtraveler may be lighter than thetraveler of van ordinary ring, for the drag on the yarn is evener, it1being produced principally -by friction of both ends of the traveleragainst the ring or race, instead of by the Weight of the traveler, asheretofore common, and consequently a lighter traveler produces as muchdrag, and thedrag is more uniform, which enablesthe production of moreeven thread, and enables it to `be Wound closer.

ItL will be obvious that .thetraveler b, acted upon by the thread at ornear the inner end Ofthbravelr,.n-stead @fatter nearfitscenter, nandnear .the topfof the Qrace, vvill move the y traveler with thegreatest uniformity 4and with the least possible tendency to vibration.

When in action, the inner end of the travveler is ,held by the lthlfadand actionof ycentrifugal -force'against thefrace at a'point above `thepoint atyvhich .the outerendof the traveler meets the race. This ringmay be made adjustableqon the .race through an ordinary holder. The raceon this ring is arranged entirely outside of a line coinciding with theinterior of the ring,and the traveler in action -moves ina circle ofgreater diameter than the diameter'of the interior portion of the ring,and this construction enables a bobbin to be wound full enough to fillthe interior of the ring; but this inclined race may vmade nearerfthecentenof nthe .rin g Awithout departing from rthis invention.

II claim- 1. A spinning-ring, Yprovidedwith .an .outwardly-inclinedrace, shapedat itsinner side `,Substantiallyas .s.eft.forth, and withitsouter l edge lovverthan the innery edge, substantially as described.

2.l A .rin`gprovded with a race outwardly inclined, substantially asshown and described,

' in combinationwitha traveler adapted, owing to the actionofcentrifugal force, to bear on and move withboth ends against the race,substantially as described.

3. As a newarticleI of manufacture, .aspin- 'ning-ring provided` with anoutwardly-inclined circular raoe,the interior diameter of which isgreater than-the smallestinterior diameter of the body ofthe ring,substan tially as described.

In testimony .whereof I have signed ,my name-to this yspecification in.the presenceof two subscribingwitnesses.
